The four-loop non–singlet anomalous dimensions are not yet completely known as a function of \(N\) . However,
a series of moments has been calculated in [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. We follow the earlier investigation in Ref. [7]} and compare these
moments with the Padé-approximation
\(P_{qq}^{3, \pm , \rm NS}(N) \approx \frac{P_{qq}^{2, \pm , \rm NS}(N)^2}{P_{qq}^{1, \pm , \rm NS}(N)},\)
